The thing that bothers me is, my failed device (one that I reset) wasn't re-registered at all, but other devices after it were registered. > > If I want to reset a device, when I'm no longer in > > probe, how do I do a reprobe?

Again, you won't need to call it yourself. Sorry, if I wasn't clear.. Say, I have a working device and somehow it fails after a while. To make it work, I have to reset this device to re-configure and start it - right? I'm not familiar with re-initialization. I appreciate if you could give me some pointers.
